I think the movement should be grid-based, like most retro RPGs. I also think that if you were to make this into a full game (and I do believe that it has to potential to be a full game), to make it more polished in art and sound. The sound is kinda meh, but the art is heavily flawed. You had the spirit with an SNES style, but it wasn't executed well. I recommend you study SNES games, and mix the nostalgic feeling of the SNES with modern polish.
